Description
A crystal controlled, low current, low
jitter and high frequency oscillator with
precise rise and fall times demanded in
networking applications. The tri-state
function on the NTH enables the output
to go high impedance. Device is pack-
aged in a 14 or an 8-pin DIP compatible
resistance welded, all metal grounded
case to reduce EMI. True SMD DIL14
versions for IR reflow are available, se-
lect option "S" in part number builder.
See separate data sheet for SMD package
dimensions.
